A headline can guide the reading of a secondary product image. A callout can draw attention to a real feature. Problems start when every piece of information competes for the same space. Decide on one main message before selecting fonts and colors.
Keep the hierarchy short
Use the headline for the central idea. Add a subtitle only when it provides context. Reserve callouts for a few specific points, and supporting copy for necessary additional information. Avoid repeating one message across every text level.
A bottle image about carrying could point out the actual handle without inventing an indestructible material or a temperature-retention specification. Benefits and technical claims need support from the seller's verified product data.
Choose colors for contrast
Text does not have to be black or white. Dark colors on light areas and light colors on dark areas can work when they remain easy to read. Inspect the exact background behind the letters rather than the overall average color of the image.
If the scene is busy, change the framing, reserve negative space or reduce the text. Do not automatically rely on large white panels behind each phrase. They may suit some compositions, but should be a deliberate design decision.
Describe callout graphics precisely
For filled icons, request small filled icons beside the supplied callout text. A style label on its own can leave room for a different interpretation. For leader lines, specify which real part they point toward and keep critical product areas clear.
A shared color for all callouts can create consistency. Headlines, subtitles and supporting copy can use their own colors as long as the composition stays coherent and legible.
Review at the size people will see
Open the result on a phone without zooming. Can you read the headline? Do callouts point to the correct components? Does text cover the product or a face? Image tools may change letters, invent words or alter a measurement, so check each phrase even when it looks plausible.
